And in the same town was a widow who repeatedly came and entreated him, saying, "`Give me justice and stop my oppressor.'

yet because she annoys me I will give her justice, to prevent her from constantly coming to pester me.'"

ἐκδικήσω ekdikēsō “I will avenge”

Do not be revengeful, my dear friends, but give way before anger; for it is written, "`Revenge belongs to Me: I will pay back,' says the Lord."

while we hold ourselves in readiness to punish every act of disobedience, as soon as ever you as a Church have fully shown your obedience.

ἐκδικῆσαι ekdikēsai “to avenge”

And now in loud voices they cried out, saying, "How long, O Sovereign Lord, the holy One and the true, dost Thou delay judgment and the taking of vengeance upon the inhabitants of the earth for our blood?"

ἐκδικεῖς ekdikeis “you avenge”

True and just are His judgments, because He has judged the great Harlot who was corrupting the whole earth with her fornication, and He has taken vengeance for the blood of His bondservants which her hands have shed."

ἐξεδίκησεν exedikēsen “He has avenged”
